“边境”常见的英文表达是 border ,它既可以作名词,也可以作动词。作名词时,主要指国家之间、地区之间的分界线或边界区域,例如:
The two countries share a long border.(这两个国家有一条很长的共同边境线。)
Soldiers were stationed along the border to prevent illegal crossings.(士兵们驻扎在边境,以防止非法越境。)
此外,frontier 也有“边境;边界;边疆”的意思,不过它更强调未开发或人烟稀少的边远地区,常带有一种探索、开拓的意味。例如:
The pioneers ventured into the frontier in search of new opportunities.(开拓者们冒险进入边疆地区,寻找新的机会。 )
